The A06B-6134-H303 is a FANUC Beta i series Servo/Spindle Amplifier Module, specifically identified as the SVPM3-15i (Beta i Servo & Spindle Module 3-axis/15kW). It is a compact, combined power supply, triple-axis servo amplifier, and spindle drive commonly used in smaller FANUC-controlled CNC machines, such as mills or lathes with 0i-MC controls.

Key Specifications & Features

• Model: Beta i SVPM3-15i (Model biSVSP 40/40/40-15).
• Function: Combined 3-axis servo drive and spindle amplifier.
• Capacity: 15 kW Spindle, with 3 axes capable of driving model βi 8 or βi 12 servo motors.
• Input Voltage: 200–230 VAC, 3-phase.
• Series: Beta i Series (often used for lower-end or small jobbing machines).
• Compatibility: Designed for FANUC Beta i servo motors and CNC systems.
• Versions: Exists in variants #A, #C, and #D, with #D being a later generation, often non-interchangeable.

Common Applications

The A06B-6134-H303 is widely used for:

• Small machine tool applications (mills and lathes).
• High-performance CNC robot motion control systems.
• Industrial automation requiring compact servo/spindle solutions.

Common Alarms and Troubleshooting

The module features self-diagnostics; common alarms include:

• Alarm 01: High internal motor temperature.
• Alarm 02: Excessive deviation between actual and commanded motor speed.
• Alarm 06: Abnormal temperature sensor or broken cable.
• Alarm 07: Over-speed (motor exceeds 115% of max allowed speed).
• Alarm 8, 9, A: High current/short circuit in amplifier, motor, or cables.

Technical Characteristics

• Cooling: Integrated fan cooling.
• Mounting: Compact panel mount.
• Construction: Rugged, designed for harsh industrial environments.
• Repairability: Extensively supported for repair and exchange due to heat dissipation issues in earlier designs.

For repairs, technical support, or replacements, the unit is often serviced by industrial electronics experts who can test the unit on closed-loop Fanuc test rigs.
